Draft Amendment 1 to IS 9081: 2024, Scope of IS 9081:2024 is as follows:This standard specifies the dimensions, materials,
tests and acceptance standards for valves and valve
accessories for tyre tubes as supplied for application
with inner tubes, and valves for use with automotive
vehicles including two wheeled vehicles, off-theroad vehicles and animal drawn vehicles. This
standard gives those dimensions of commonly used
valves which are important for fitment and
interchangeability. Although the tests for valve
cores have been included, the dimensions for valve
core chambers have not been included since the
same is covered in IS/ISO 20562 ‘Tyre valves —
ISO core chambers no. 1, no. 2, no. 3 and no. 4’.
Valve caps are also not covered in this standard since
these are covered by IS 9453 : 2014 ‘Valve caps for
tyre tube valves for automotive vehicles —
Specification.’ |
